Unfortunately, my copy is also very slow when loading. Reading is ok. However, it crashes a lot and scrolling through the page number takes forever.
Maybe it's the software. Anyway,
https://www.dibizentral.ch (Onleihe) told me that Tolino is currently having problems.
In the meantime I have got used to the slowness. (Every mobile phone, and I mean every mobile phone, is faster).
